A connecting section for a hydraulic connection of the working part and of the intensifier part provides a connecting line for passage of hydraulic fluid between the working part and the intensifier part. The connecting section includes an adapter component which can be mounted on the working part and the intensifier part, and in the interior of which the connecting line is formed. In the mounted state of the adapter component, an opening, which is provided at the side on the working part, of a hydraulic chamber of the working part is connected, via the connecting line, to an opening, which is provided at the side on the intensifier part, of a hydraulic chamber of the intensifier part.

Abstract: A method and tool for producing a press joint connection, in which portions of the radial lateral walls of an opening of a die are configured as flexible displaceable segments, whereas other sections, when viewed from a periphery of the opening, remain rigidly connected to the die.

Abstract: The tool, for bonding two plates together, has a punch (1) and a die (2) each as two-part structures with a positive fit between the two parts. One part (8, 13), as a tool which acts directly on the plate workpieces (3), is of a harder material than the other part (7, 12) which acts as a tool holder. The punch and die are divided into their two parts across the working direction.

Abstract: Proposed is a hydro-pneumatic pressure transformation device with a working piston (3) and a transformer piston (17) for transforming the pressure exerted upon the working piston (3), wherein the transformer piston (17) features a working stroke chamber (19) for the power stroke and a return stroke chamber (15) for the return stroke, and wherein the working stroke chamber (19) can be subjected to an operating pressure for the power stroke. According to the invention, pressurization means are provided for changing over the return stroke chamber (15) between a low pressure that lies at least approximately in the range of atmospheric pressure or at atmospheric pressure and an intermediate pressure that lies between the low pressure and the operating pressure during the course of the power stroke and the return stroke. A method for operating a hydro-pneumatic device is also proposed.

Abstract: The invention relates to a method and tool for producing a press joint connection. According to the invention, portions of the radial lateral walls of the matrix opening (3) are configured as flexible displaceable segments, whereas other sections (5), when viewed from the periphery of the matrix opening (3), remain rigidly connected to the die.

Abstract: A press and to a guide for a guide element of a press are disclosed. A tool receiving element is integrated into the guide element such that the tool can be guided in a wear-resistant manner.

Abstract: An apparatus and method for joining the assembly components that allows for the adjustment of working stroke and press forces during operation in order to control the thickness of the resulting joint point.

Abstract: A hydropneumatic pressure transmission device having a working piston and a transmitter piston for pressure transmission to the working piston is proposed, with the working piston being guided in a housing space in such a way that, coupled to the movement of the working piston, hydraulic fluid must flow from a first region via a first connecting section into a second region. According to the invention, a switchable second connecting section is provided so as to be connected parallel to the first connecting section.

Abstract: A tool, for making clinching connections, which has a multi-part matrix with matrix sheathing pieces that move to the outside and with counteracting springs. These springs are one-piece connected with each other through a connecting section. There are at least three sheathing pieces which are arranged axially symmetric around the centerline of the matrix.

Abstract: Proposed is a method, as well as a tool, for performing a process to create a joint in which wall sections 8 of work opening 4 of die 5 are designed to yield, and in which cold hardening of the compressed material is achieved by a stop element after a specified distance has been traversed.

Abstract: A tool, in particular for production of overlap joints, with a multi-component die, with outwardly yielding die sleeve pieces (2) and opposing individual springs (6), which are connected to each other in one piece by a connecting section (7), whereby at least three sleeve pieces (2) are provided, arranged asymmetrically around the mid-axis of the die.

Abstract: The tool, for bonding two plates together, has a punch (1) and a die (2) each as two-part structures with a positive fit between the two parts. One part (8, 13), as a tool which acts directly on the plate workpieces (3), is of a harder material than the other part (7, 12) which acts as a tool holder. The punch and die are divided into their two parts across the working direction.

Abstract: The invention relates to a method, a tool and a punch (1) for joining a sunken punch to one or more metal plates (2, 3). According to said method, in a single step, the plate or plates are deep-drawn into a deep-draw opening (5) of a female mould or then possibly crushed so that the displaced material fixes and joins the punch (1) to the plate or plates in a positive fit. The punch (1) may present further possibilities for engagement for creating a connection to other components.

Said seal is arranged between working pistons (2) and the cylinder bore which accommodates said pressure intensifier or in a bore hole (15) between the working chamber (3) and a storage area (14), whereby the radial seals consist of viscoplastic and flexible synthetic material.

Abstract: An accessory device for cameras having a housing, a cylindrical opening whose diameter corresponds to at least the diameter of a camera objective, a rotatably-journaled, transparent protective element for closing off the housing, and an electric motor for rotating the protective element. The electric motor comprises a casing surrounding the protective element to form a rotor of the electric motor. The stator windings of the electric motor are attached to the housing.

Abstract: A method for topping off a reservoir chamber of a hydropneumatic pressure intensifier with oil, and the embodiment of such a hydropneumatic pressure intensifier, in which the reservoir chamber has a vent bore, which being usable as an overflow protection means as well is controlled by a flow control valve and is uncovered preferably by the reservoir piston in its outset position. In the event of improper aeration, the reservoir piston is thrust against a stop determining its extreme position, in a further feature of the invention a second vent bore can be uncovered by such movement.
